Quality Control For Two Types Of Radiotherapy Multileaf Collimators
Journal Title: RA Journal Of Applied Research - Year 2015, Vol 1, Issue 9
Abstract
The purpose of our study was to describe the performance characteristics of two MLC systems (Elekta and Siemens) having different leaf width respectively to improve the available data. Furthermore, the work suggests an adequate QA program to be performed during routine treatment delivery. Methods and Material: The Leaf leakage, tongueand-groove effect, identification between light field and radiation field , measurement of penumbra for all borders of MLC leaves, Penumbra measurements in the direction of leaf motion, Penumbra measurements for stepped MLC edges, Precise position of MLCs of a highenergy photon (6 MV) Elekta and Siemens linear accelerator were measured using Kodak X-Omat V film.
